The cherry bomb is loud if you have a full system, if the rest of the system is standard the cherry bomb will give a nice deep tone without sounding like you have no exhaust.
Not really. It'l require the mounts to be welded on and possibly a secure connection to the existing or new exhaust pipe, which isn't much work.
Any custom exhaust place will carry out the same process when they make a rear silencer. Most exhaust places or welders won't have any problems doing this task.
The 15/20bhp gain they state in the listing is a load of crap though
I personally think you should get a janspeed or sportex backbox designed for the car. What you spend more on the box, you'l spend less on installation costs.
i might get 1 next week like i say £40 aint alot if i do i let ya see and hear it joe wont be that hard or cost that much to have it welded where it needs to be
